Usage

In most cases, you can refer to the confluent-kafka-python documentation for guidance. Every keyword in ConfluentKafkaLibrary is designed to match the corresponding Python functions. If you are unsure about the pre-configured keywords, please visit the robotframework-ConfluentKafkaLibrary documentation. The Kafka team maintains the up-to-date documentation for configuration properties and their values here.

• You can find basic usage examples in the ./examples/test.robot
• For more complex examples, such as handling byte data from a topic, using multiple consumers, or running threaded avro consumers, please refer to the documentation.

Testing

• The library is tested using black-box tests written in Robot Framework.
  • You can find the test files in the examples/ directory directory.
• For testing, a dockerized enterprise Kafka platform with schema registry support and REST proxy is used. The platform is deployed and tested for each pull request and merge to the master branch.
  • See docker-compose.yml file with the necessary configuration.
• Tests are divided into the following files:
  • test.robot - Basic tests to verify functionality of the Consumer and Producer.
  • test_adminclient.robot - Verifications of admin client functionality.
  • test_avro.robot - Verifications of avro and serializers functionality.
• Not executable example of oauth usage can be found here
  • Update of deployment https://github.com/robooo/robotframework-ConfluentKafkaLibrary/issues/21 is required.
• The core testing logic involves producing data to Kafka, connecting one consumer in a thread, and working with the results in specific test cases.
